' RADIATOR.

Specification of Letters Patent.

Patented Mar. 6, 1917.

Application filed October 23, 1915. Serial No. 57,457.

To all whom it may concern:

Be it known that I, JOHN.B. GABRIELSON, a subject of the King of Sweden,residing at the city of Jamestown, in the county of Chautauqua and Stateof New York, have invented certain new and useful Improvements inRadiators, of which the following, taken in connection with theaccompanying drawings, is a specification.

The invention relates to radiators for motor driven vehicles, and theobject of the improvement is to provide a radiator core construction inwhich the water ways are substantially unobstructed yet provision ismade for alining and holding the different plates upon one another inspaced relation in assembling said plates so as to form zigzag orserpentine water ways which extend around crosswise air flues so thatwhen the sheets are assembled together they may be dipped in a solderbath thereby uniting all the parts in perfect alinement and in thespaced relation required for the thinv sheet metal water ways; and theinvention consists in the novel features and combinations hereinafterset forth and claimed.

In the drawings, Figure 1 is an elevation of the front end of anautomobile showing a portion of the radiator core with the air fluestherethrough. Fig. 2 is a perspective view of a portion of the airflues, the upper edge being shown in sectional perspective at line W inFig. 3. Fig. 3 is an enlarged elevation of a portion of the front of theradiator core, a portion of said core being shown in vertical section atline Z Z in Fig. 4. Fig. 4 is a sectional view at line W W in Fig. 3.Fig. 5 is a sectional view at line Y Y in Fig. 3; and Fig. 6 is asectional view at line X X in Fig. 3.

Like characters of reference refer to corresponding parts in the severalviews.

-The numeral 10 designates the radiator which is made the size desiredfor cooling the water in the motor. The numeral 11 designates the casingor hood for: the core 12, which casing has a reservoir 13 at the top ofthe core 12 and a reservoir 14 beneath the core 12 from which the waterreturns to the motor after passing through the water ways 15 of theradiator core from the 'top reservoir 13.

The core 12 of the radiator is made up of zigzag water ways 15, theopposite walls of which are formed by strips of sheet metal 16 which arebent in the serpentine or zigzag' shape shown, the edges 17 beingattached to one another by dipping in a solder bath while the centralportion from the top to the bottom of each metal sheet '16 isbent tofirst one side and then the other as hereinafter described, so as toform a water way 15 of substantially uniform volume throughout itsentire course from the top to the bottom of the radiator, that is, onein which the side walls are substantially equally spaced from oneanother and are bent in the same serpentine form. 1

The shape or design of each pair of serpentine metal sheets consists ofvertically flat spaced portions 18 for contacting surfaces of theadjacent sheets, said fiat vertical contact portions being connected bya double or reverse curve formed by the union of a convex and concaveline, which is often called an ogee outline. The design gives a pleasingform to the air tubes and provides a strong bracing construction for thecontinuous sheet metal strips 16 which form the walls of the water waysand a plurality of which make up the core 12.

In order that the flat surfaces 18 may be continuous from the. front tothe rear of the radiator core 12 and form a strong bracing support, itis apparent that the bent out or spaced central portion for the waterway must be placed on alternate sides of said straight portions 18. Inorder to change from one flat contacting surface '18 to the full innersidewise bend, said sidewise bend in each sheet metal strip must changefrom the straight strip of metal in which there is no sidewise bend to afull sidewise bend which is the full crosswise width of the water way.This is preferably accomplished gradually throughout the ogee bend;hence the side walls throughout the ogee bend would start with the fullbend on one side and no bend on the other and gradually change to theopposite sidewise bend in l which the sheet of metal which had nosideother, each of the two strips forming a zigzag water Way having theteats so contacting as to hold said sheets in the spaced relationrequired for a water way of uni} form volume. It is apparent that theline of sidewise projecting teats 21 and 21 form centering or aliningpoints in the assemblage of the strips 16 which hold said strips firmlyin perfect alinement so that the entire core may be quickly and easilyassembled and dipped in the solder bath, thereby making the contactingalinement permanent 1 by attaching said sheets firmly to one anthe teats21 of said inner other.

. The inner plates 16 have contacting flat, top, bottom and intermediatesurfaces and plates snugly nest one within the other, while the teats 21of the outer plates 16 cooperate with the teats 21 and serve to hold theouter plates spaced from the inner plates as shown in Fig. 4.

I claim as new:

-1. In a radiator an inner pair of plates having top, bottom andintermediate flat contacting surfaces and shaped to .conjointly form airflues between said surfaces, said top, bottom and intermediate surfaceshaving interengaging concavo-convex teats, said teats being snuglynested one within the other respectively, and an outer pair of plateshaving top, bottom and intermediate flat surfaces registering with thecorresponding surfaces of the inner plates and forming water passageswith the latter, said fiat surfaces of the outer plates havingconcavo-convex teats registering with the corresponding teats of theinner plates, the convex faces of the teats of one outer plate beingshaped and engaged in the concavities of the teats of the adjacent innerplate so as to space said last named plates, and the convex faces of theteats of the other nameaa inner plate being shaped and engaged in theconcavities of the teats of the other outer plate so as to space saidlast named plates.

2. In a radiator, inner and outer-"spaced pairs of plates shaped toprovide inner air flues and outer water passages, the inner pair ofplates having'fiat contacting surfaces formed with concavo-convex teatssnugly nested one within the other, the outer pair of plates having flatsurfaces disposed opposite'the respective flat surfaces of 'the innerplates, and concavo-conver: teats formed on the flat surfaces of theouter plates and registering with-the correspond ing teats of the innerplates, the convex faces of the teats of one outer plate being engagedin the concavities of the teats of one of the inner plates and shaped tospace said last named plates and the convex faces of the teats of theother inner plate being engaged in the concavities of the teats of theother outer plate and shaped to space said last named plates.

3. In a radiator, an inner pair of plates having top, bottom andintermediate flat contacting surfaces, and substan- 'tially S-shaped'connecting surfaces between the successive flat surfaces, an outer pairof plates having top, bottom and intermediate flat surfaces registeringwith the corresponding flat surfaces of the inner plates andsubstantially S-shaped connecting surfaces between the successive fiatsurfaces of the outer plates which last named s-shaped parts registerwith parts to form water passages in conjunction therewith which waterpassages cause a retarded and serpentine flow of the water, thecontacting surfaces of the inner pair of plates having teats snuglynested one within the other, and teats on the fiat surfaces of the outerplates cooperating with the teats of the .inner plates to maintain theouter plates in their said spaced relation to the inner pair of plates.

In testimony whereof I have afiixed my signature in the presence of twowitnesses.
